6, 7, 8, 9, lo, or more Sides 3 fo that I 

 n'sed nor enlarge more on it. 



I fliall only give one Example more of Com- 

 pound Figures, which are us'd very much 

 with us in Gardening. Let ir be Figure the 

 icrfi, Plate the 23d, composM of a Square 

 and a Semi-cirde at each End. 



Having already taught ^ow to meafure a 

 Square and a Semi-circle, there is the lefs 

 Occafion to enlarge here. Firft meafure the 

 Square, and then the two Semi-circles, and 

 adding them together, it gives the Content. 



Thus the Length a b, or c d, loc Fpot, 

 multiply'dby a c, or b d, 60 is 600, and the 

 Semi-circles 196 Foot, make in all 796 Foot 

 fuperfiqikl in the Area of that Compound Fi- 

 gure. ' ' / /'"^ 



I fliall now finifli this Chapter with a fliort 

 Sketch of a Meafuring-Book Abftrad, and of 

 a Bill, or Computation of Work to be done 

 by any Gardener, d^c. which are the origi- 

 nal Foundation of Minutes for a Bill, or 

 Contrad-, and for the Scheme and Schedule 

 thereto commonly annex'd. 



You are then, upon the Paper, if it be for 

 an Eftimate,x)r upon the Ground, if the Work 

 be done, and it be a Bill, and not an Eftj- 

 mate, to meafure the Length and Breadth oi 

 every Particular 5 and caft up, and place all 

 the Dimenfions in a corred Method, that you 

 may the eafier abftraft them into general
